Now I’ve followed up with my own weathergrams. Earlier this month (the first week of January 2015) I was able to do this on Goose Pond (near Chatham on Cape Cod).

My resources were mostly what I had on hand and carried from Hawai’i; strips I cut from a 25 year old roll of white “butcher” paper and garden twine. Today this Goose Pond area is under snow (the January blizzard of 2015). The photos are of course pre-blizzard. All counted eventually there were twelve weathergrams on this small oak tree above Goose Pond.
